Clandestine_Blaze writes: Chinese police have arrested 5,394 people — with another 4,186 criminal cases in the works — in one of the largest crackdowns on Internet porn in the country. Even more arrests were expected in 2010, according to the Ministry of Public Security's website (In Chinese or Google translated into English). According to the Reuters article on the crackdown, one of the justifications was that the pornography was 'threatening the emotional health of children.'

From the English translation of the Ministry of Public Security's website linked above, it appears that certain provinces are also offering 1,000 yuan and 2,000 yuan awards, per person, for reporting illegal websites to the Government.
